Looks like hindi naman pala nagkakalayo ang tips natin. Here's mine:

1. Waiters - Depending on the service, 20-50, if may SC but still good service minsan I still give the loose change.
2. Gas station attendants - Usually 5-10 for windshield and air.
3. Parking is usually 20-40
4. Mechanics - Usually 50 for minor work, 100-200 for major.
5. Hair stylists - Usually around 100 if I like the cut, but sometimes I no longer give pag mahal masyado ung charge.
6. Car wash - I'm usually charged 90, and I'd usually pay 100
7. Supermarket Baggers - 10-20 depending on how much bags there are.

I am sometimes a cheapo though, I must admit. May times kasi na medyo short talaga sa cash or wala kang pwedeng bigay na barya, so minsan di rin ako nakakabigay.
